Serum carbamylated albumin (C-Alb) levels are associated with excess mortality in patients with diabetic end-stage renal disease. To gain insight into the pathophysiology of carbamylation, we determined associations between C-Alb and causes of death in patients on chronic hemodialysis. The Die Deutsche Diabetes Dialyse Studie (4D study) was a randomized controlled trial testing the effects of a...
Leaf metabolites, adenylates, and Rubisco activation were studied in two transgenic tobacco (Nicotiana tabacum L. cv W38) types. Plants with reduced amounts of cytochrome b/f complex (anti-b/f) have impaired electron transport and a low transthylakoid pH gradient that restrict ATP and NADPH synthesis. Plants with reduced glyceraldehyde 3-phosphate dehydrogenase (anti-GAPDH) have a decreased cap...
DNA Alkylation is thought to be the reason for the efficacy of lomustine while carbamylation has been implicated as the cause for the side effects seen with lomustine treatment such as hepatotoxicity. In the alkylation study we show that lomustine and its metabolites form similar levels of the DNA adducts N⁷ hydroxyethylguanine and O⁶ hydroxyethyldeoxyguanosine. In terms of carbamylation, lomus...
There is an emerging and significant body of research that suggests that MPO (myeloperoxidase) may be a critical mediator in dysfunctional lipoprotein formation and, hence, atherogenic initiation and progression. MPO is a haem peroxidase found in leucocytes and is abundant in macrophages surrounding atherosclerotic lesions. Several lines of evidence support the role of MPO-mediated carbamylatio...
Traditional risk factors fail to explain the increased risk for cardiovascular morbidity and mortality in ESRD. Cyanate, a reactive electrophilic species in equilibrium with urea, posttranslationally modifies proteins through a process called carbamylation, which promotes atherosclerosis. The plasma level of protein-bound homocitrulline (PBHCit), which results from carbamylation, predicts major...
Heptylphysostigmine is in advanced clinical trial as a drug for Alzheimer's disease. 8-Morpholinooctylphysostigmine and 8-(cis-2,6-dimethylmorpholino)octylphysostigmine are currently undergoing pre-clinical evaluation. The mechanism of action of these compounds in the inhibition of acetylcholinesterase has been investigated. All the examined compounds display non competitive-like kinetics of in...
The discovery that citrullination was crucial for the recognition of antigens by the most disease-specific class of autoantibodies in rheumatoid arthritis (RA) had a huge impact on studies aimed at understanding autoimmunity in this disease. In addition to the detailed characterization of anti-citrullinated protein antibodies, various studies have addressed the identity of citrullinated antigen...
